feat(client): 移动壳基建——底部 5 tab + 我的 hub + 统一底部 sheet + 移动组件四件套
对齐移动原型体系（m-*.html）的 Stage 0 共享基建，桌面形态零改动： - 导航：router 新增 branch 9（/me 我的 + /me/license 授权屏）；窄屏 tab 根 （库存/入库/出库/财务/我的）出底部 MTabBar，二级屏隐藏 tabbar + 顶栏返回箭头 （PopScope 拦系统返回键防退 app）；窄屏 Drawer/汉堡删除；窄屏顶栏对齐 m-top （标题 + 主题/通知铃/头像→我的） - sheet：showMSheet（grip/标题/86vh/键盘避让）+ showAdaptiveSheet；六个共享 弹层呈现函数加窄屏 sheet 分支（订单/往来/财务往来/商品编辑抽屉 + 退单/登记收支 dialog 的 asSheet 形态） - 徽章：DsBadge/StatusPill/StatusBadge 加图标变体（默认圆点零漂移）+ status_icon_map 转录原型 BADGE_ICON 28 词 - 组件：MKpiGrid（2×2 可点 KPI）/ MSearchRow（搜索+状态钮+详搜钮）/ MHubGroup（hub 入口组）/ showThemeSheet（主题外观 sheet） - 授权：_LicensePanel/_SettingsCard 抽取为公共 LicensePanel/SettingsCard， 窄屏授权跳转 /me/license - golden：app_shell_mobile + me 各三主题（390×844@2x）；全量 259 测试绿， check_ds_code / check-l1-sync 闸过 Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
